Kate Upton might finally make the cover of Vogue. The voluptuous swimsuit model has already graced the covers of British and Italian Vogue — not to mention the Sports Illustrated Swimsuit Issue two years in a row. But some supercilious fashionistas sneer that Upton is too curvy for couture. Sources say editrix Anna Wintour is close to putting a new shot taken by Mario Testino on an upcoming cover, possibly its June edition. A Vogue spokesman said, “We don’t ever comment on future covers.”
